so I am doing some "low level" stuff successfuly for the first time ever w/ my arduinos! yay for me. anyways I am scaling down from a mega to a smaller one, and might need to use timer0. Is there a good rundown somewhere of core functions that utilize timer0? I may be changing the prescaler and want to know which functions are no longer useable when I do that, and that none of them are needed by me.
Have you looked at the playground already?
I have found lots of scattered info, wondering if there is a difinitive source, or a smart guy here.
